Premium 100-500VAC Electrical Voltage Tester Pen Tool

Product Overview:

Ensure complete electrical safety and reliable testing with our Premium 100-500VAC Test Pen. Designed for both professional electricians and household maintenance, this multi-functional voltage tester pencil accurately detects AC voltage while serving as a dependable slotted screwdriver. Featuring a high-frequency heat-treated steel blade, high-visibility neon indicator, and an insulated ergonomic casing, it delivers exceptional safety, durability, and peace of mind on every electrical job.

Key Features:

Accurate 100–500VAC Voltage Detection: Easily detects live AC circuits, identifies live vs. neutral wires, and locates circuit breaks with clear, instant neon lamp illumination.

Heat-Treated Heavy-Duty Blade: The screwdriver tip is forged from high-quality alloy steel and undergoes precision high-frequency heat treatment, ensuring high torque strength, anti-wear durability, and resistance to deformation under fastening force.

Enhanced Electrical Safety: Built-in high-safety current-limiting resistor ensures human body contact current is far below safe thresholds (less than 1mA), providing 100% shock-free testing.

Crystal-Clear Insulated Handle: Made of high-impact, transparent insulating plastic with an integrated pocket clip for convenient carrying and easy viewing of the glowing indicator from any angle.

Dual-Function Utility: Functions seamlessly as both an AC voltage detector and a precision terminal block screwdriver.

FAQ

Q1: How does this test pen safely detect voltage without shocking the user?

A: When you touch the metal end cap and contact a live wire with the tip, current flows through the blade, a high-value safety resistor (typically >1MΩ), and the neon tube into your body to ground. The resistor drops the current to micro-amps (well below safety limits), lighting the bulb safely without any sensation of shock.

Q2: Can this test pen be used as a regular screwdriver?

A: Yes. Unlike cheap testers made from soft iron, our blade is forged and heat-treated to professional screwdriver hardness, allowing you to tighten and loosen terminal screws without deforming the tip.

Q3: Does this test pen require batteries to operate?

A: No. It is an electro-optic neon tube tester that operates purely on the electrostatic potential of the AC circuit (100–500V AC), requiring no batteries or external power.

Q4: What is the MOQ and delivery time for OEM custom orders?

A: The standard MOQ for custom branded display boxes or blister cards is 2,000–3,000 pcs. The average mass production turnaround is 20–30 days upon artwork confirmation.
